Some have recommended lang-8.com or italki.com in the past, though I have no firsthand experience with them. But please note that requests for resources are also off-topic :).

Try englishforums.com. They like to proofread.

If you already own a copy of Microsoft Word, or OpenOffice.org, it will do some proofreading automatically.

The short and unpopular response would be that if you need professional-quality writing, you should hire a professional-quality writer or editor, rather than cheap, anonymous substitutes. :)

Are these for free or do we need to pay registration fee to get an account?
– Jony AgarwalJan 7 '16 at 16:47

@JonyAgarwal You can use them for free with an accurate fix but some have an option for subscribing or using a more advanced fix. Paper Rater is probably the best one. Just click the free use.

Just tried it. Looks great. However, I still wish proofreading was available in EL&U. Some of the tips given after the review are pretty complex !

@JonyAgarwal You may be able to ask a specific question about a specific suggestion which has come from proof-reading. Possibly.

It works on the principle of reciprocity: you proofread a guy or gal's posts in your language, they proofread writing in theirs. Furthermore, the more you've proofread, the higher your reputation is, and this also attracts readers and proofreaders.

You'll need to create a free account. Click on "Forums", the rightmost item in the main menu and scroll down to

Essay, Report & Composition Writing

where you can post your text and people will give you advice even beyond simple proofreading. The site also has an internal messaging system, which can be helpful for one-on-one conversations about your writing. I don't know how many "editors" avail themselves of that facility. I used to.

Give Typely a try. It is a free proofreading application that you can use right away. It has been featured on the frontpage of many news aggregators and is already stable and strong.

Our main focus is not grammar but we do catch a lot of mistakes while performing over a thousand checks on any given document. You can also check your writing’s sentiment, required education for audience (grade) or reading ease.
